Today was Jack's 18th birthday. He awoke in time to do some studying and get ready for school. He walked naked to the bathroom.
His sister met him in the hall, she too was naked. That was not at all unusual because the family were nudists and never wore clothes around the house except when guests were there. Since some of their friends were also nudists, they often wore no clothes when guests were present.
"Good morning, Jack, and happy birthday", said Beverly brightly with a smirk that implied something but Jack did not know what.
"What's up with you?" he asked.
"You'll see", she said cryptically with a smile and a wink and walked to her room.
Jack took care of business and returned to his room. He was reading an article about robots when his mom came in as naked as he and came over, hugged him tightly to her bosom and wished him a happy birthday and said, "Don't go to school today. I want this to be the special birthday as it should be."
"I'll need an excuse, you know."
"Yes, dear, I already took care of this. You have an unexpected outbreak and we do not know if it is contagious", she responded.
"What would that be?"
"You'll see. I'm fixing breakfast. Be down in about 10 minutes, OK."
"OK, Mom", Jack responded somewhat confused about being permitted to stay home from school.
His mother had barely left the room when Liz, a girl he had grown up with and came in and said, "I have your birthday present for you", while she held her hands behind her back and twisted back and forth like a little girl. Then she turned and closed the door.
"What? Is it that much of a secret?"
"Sort of, but when I turned 18 last year, my mom gave me a day off from school like your mom is you and now I am staying home to spend the day with you on your special day."
"OK," said Jack with a bit of a question of 'What's up with this?' in his voice.
"OK, I need you to stand", said Liz as she began unbuttoning the dress she was wearing, revealing that she had no bra on and then she removed it revealing a thong panty.
Jack stood slowly wondering what this was going to be.
"What? I thought you were going to give me a present."
Liz responded by kneeling down in front of him, taking his cock in her hand and leaning forward to take it in her mouth.
"Wait a minute!" Jack exclaimed. "We can't do this."
Liz looked up his well formed chest, and said, "We couldn't but now you are 18 and I am 18 so we can do what we want."
"Bu... . But! But, you and I aren't even dating."
"Yes, Jack, and we are adults. I'm going to suck you off for your birthday and that's the end of it."
"What if Mom finds out. They'll kill us."
"Not to worry. I told your mom I wanted 10 minutes to give you your present in private. She won't bother us." Then she put his cock in her mouth and began to stroke and suck it. In seconds it had grown hard and as big as ever.
Liz was really good at this, Jack thought. So he relaxed and let her have her way. She withdrew to the head, licked it and then placed it in her mouth again taking it all the way in. He couldn't believe it. He knew he was not huge but he was 7 inches and she was small. As she bobbed up and down, she pressed her tongue to the underside keeping her tongue pressed to the vein on its underside and stimulating the underside of the head as she came up. It wasn't long before his balls contracted and he felt the rising cum in his perineum. Then seconds later his cum shot into Liz's mouth with incredible force. Such force that she choked a bit and some leaked from her mouth. She recovered, groaned in satisfaction and swallowed. He shot several more loads and she swallowed all of them. He groaned because he felt like he had never been so turned on.
When all was done, Liz licked up and down his shaft, over his balls and cleaned all she could off him. Instead of his cock becoming limp, it just got harder.
Liz got up, hugged him closely, gave his butt a slap and said, "Let's go have some breakfast", and walked out of the room naked.
"I can't go down like this", Jack protested with a gesture toward his very erect cock.
"Sure you can. We've all seen it hard before in the morning. Just joke about your morning wood."
She then took hold of his cock and began to lead him down the hall to the kitchen. He tried to get her to let go without a tussle but she wouldn't. Just as they were turning into the kitchen, Liz announced, "Mom, here's the birthday boy." Then she let go.
Mom turned from the stove dressed in her apron which made her sexy as hell. Jack had noticed this a good bit but dismissed his thoughts as incestuous. But the sight made his cock twitch, a detail not missed by his mother who smiled and then said, "I see you have a bit of morning wood this morning, Jack. Have a seat. Breakfast is almost ready."
They ate a leisurely breakfast and Miranda informed them that she had called them off from school. Jack protested that he had ball practice that afternoon. "Yes, Jack, I took care of that also. This is your 18th birthday and Liz and I plan to make it a very memorable day."
